Constraining LLTB models with galaxy cluster counts from next generation surveys
Ziad Sakr, Ana Carvalho, Antonio Da Silva +7
The Universe's assumed homogeneity and isotropy is known as the cosmological principle. It is one of the assumptions that lead to the Friedmann-Lema\^ıtre-Robertson-Walker (FLRW) m…
The two-mode puzzle: Confronting self-interacting neutrinos with the full shape of the galaxy power spectrum
David Camarena, Francis-Yan Cyr-Racine, John Houghteling
A cosmological scenario in which the onset of neutrino free streaming in the early Universe is delayed until close to the epoch of matter-radiation equality has been shown to provi…
The tension in the absolute magnitude of Type Ia supernovae
David Camarena, Valerio Marra
This study aims to elucidate the tension in the Hubble constant (), a key metric in cosmology representing the universe's expansion rate. Conflicting results from independent…
Bayesian analysis of a Unified Dark Matter model with transition: can it alleviate the tension?
Emmanuel Frion, David Camarena, Leonardo Giani +4
We consider cosmological models in which Dark Matter (DM) and Dark Energy (DE) are described by a single component, dubbed Unified Dark Matter (UDM) models, in which the DE-like pa…
